No, you did not show the entire error message.  If it includes
a locus, ie., 'EQUIVALENCE at (1)', then a line of code was spit
out.  That's part of the error message.

This isn't the exact command line.  There is no filename listed.

Drop the -fno-f2c.  It's not needed because it's the default.
Add '-Wall -std=f95', and fix any problems.  Why are you using
f77-cpp-input?

It would be nice if you actually wrote standard conforming Fortran.
